Every Chinese humanoid company makes a technology stack choice: which operating system, which AI model, which sector. Most chose Android or custom Linux. Leju Robotics chose Huawei, HarmonyOS as the operating system and Pangu as the foundation AI model. The result in 2025: 577 units delivered, 178 million yuan in revenue ($24.5M), 12x year-over-year growth, and 1.5 billion yuan in new funding. KUAVO is growing faster than any other Chinese humanoid company by revenue percentage, and the Huawei integration is the differentiation that drives that growth in China’s Huawei-infrastructure-heavy enterprise market.

HarmonyOS Integration: Technical Detail
HarmonyOS is a distributed operating system, designed to share state across IoT devices, gateways, displays, and industrial controllers natively. In a factory running Huawei infrastructure, KUAVO integrates without additional middleware:
- Native device mesh: HarmonyOS factory gateways read KUAVO task state, sensor data, and position directly, no custom API bridge required
- Display integration: HarmonyOS panels show KUAVO operational status natively
- PLC connectivity: HarmonyOS industrial controllers exchange data with KUAVO at native bus latency
- Security: HarmonyOS end-to-end encryption between all connected devices including KUAVO
For Chinese factories standardized on Huawei infrastructure, a significant and growing segment, KUAVO integration is dramatically simpler than deploying Android or Linux robots requiring custom middleware bridges.
Huawei Pangu AI: Capabilities for KUAVO
- Mandarin instruction comprehension: trained on Chinese industrial text, understands technical vocabulary, regional operator speech variants, and manufacturing-domain Mandarin with greater accuracy than English-trained models fine-tuned for Chinese
- Manufacturing domain knowledge: trained on Chinese industrial standards, manufacturing process documentation, and quality control procedures relevant to KUAVO task planning
- Continuous improvement: every Pangu update automatically improves KUAVO AI capabilities without Leju-specific retraining
- Multimodal processing: camera streams + sensor data + language instructions in a single multimodal context at inference time
- Reasoning: Pangu handles multi-step task decomposition, “assemble the valve on workstation 3 using the parts in bin 7A” decomposes into a navigation + manipulation sequence without explicit programming
National Games Torchbearer 2025
KUAVO was selected as torchbearer for the Chinese National Games in 2025, carrying the ceremonial torch in a public relay segment alongside Olympic athletes, covered live by CCTV. State broadcaster selection as a technology representative in national symbolism is the highest-visibility endorsement available to a Chinese technology company. It drives procurement decisions from state-owned enterprise customers, China’s largest industrial buyers, more effectively than any trade show demonstration.
